CyberSKA Portal Release Notes - v1.0.5 - February 9, 2011

Below is a summary of the latest CyberSKA portal release (v1.0.5) on February 9, 2010. An updated FITS viewer (v0.4.1) was also released at the same time.

Many new and exciting features have been included in this release. One of the main new collaboration features is support for subgroups. Subgroups can be created within a group to organize group members based on different roles, teams or projects that they may be working on. A subgroup has the same functionality/features as a normal group complete with it's own group page and resources, but cannot subdivided into further subgroups currently.

Another new collaboration feature is support for organizing files in a hierarchical directory structure. Previously, only a single level of directories was supported.

The FITS viewer also has several significant new features. It now supports 2D Gaussian fitting, saving a screenshot to your CyberSKA files, and a permalink feature that lets you share a link with others that will load the image with the same configuration (i.e., zoom, histogram, colormap) that you are currently viewing the image with.

There are many other new features/enhancements in this release. For more details please see the list below:
